At some point in the pregnancy most women will wonder whether their baby is normal. They may also consider what would I do if something were wrong. These are the most common concerns for pregnant women.
The feelings may be instinctive, possibly being related to unexplainable thoughts like "Do I deserve a healthy baby?" Or there may be concrete reasons such as disorders that run in your or your partner's family.
Often they are triggered unexpectedly by a caregiver offering screening tests for abnormalities, even though the thought had not even entered your mind. This can be quite confronting and challenge your feelings about your body's ability to produce a healthy baby. Unfortunately no amount of tests can give you an ironclad guarantee, but thankfully most babies are born well and healthy.
Concerns about relationship changes
Relationship changes to some degree are inevitable. Having a baby can either disrupt a relationship or strengthen it (or both!). Your relationship moves from being just the two of you learning about each other in the beginning, falling in love, accepting each other's idiosyncrasies. You relate closely to just one other person, exploring what works and changing what doesn't. The same process happens when you become three or four in the case of twins. Keep talking, communicate how you are feeling, this can be hard in the early weeks-months with little sleep and feelings of frustrations, or loneliness.
Your new role as a mother comes suddenly, with no job description, no orientation, no training and you are often expected to do it perfectly, cheerfully and effortlessly (you didn't even put in a resume!) No wonder so many women feel they lose their identity and struggle to nurture their other relationships.
Many women also reassess their relationships with their own mothers when pregnant. You may have a new respect for her or your relationship may evolve to be more one of kinship.
